answer HOT2000 User Guide
7.15.1 to 7.15.3, Appendix F
Efficiency Rating type:
Select energy factor or uniform energy factor, if unknown, select energy factor
If the Energy Factor radio button was selected, then select User specified to enter the
assessed Energy Factor. Alternatively, select Standby to enter the efficiency by Standby
Heat Loss, Thermal Efficiency and Input Capacity. Data must be entered into all three of
these fields to define the efficiency by standby heat loss unless the Energy Source is
Electricity. In that case, the Thermal Efficiency is automatically set to 98%. If the
efficiency is unknown, use the HOT2000 default.
For heat pump water heaters only integrated heat pump water heaters located inside
building envelope can be modelled in H2K
Do not use Tankless heat pump or Heat pump for modelling

correct answer Technical Procedures
3.5.11
Ventilation systems are defined as either a mechanical whole-house ventilation systems
or as supplemental components.
Whole-house ventilation system circulates air throughout the entire house
Ventilation equipment that operates independent of the whole-house system is
considered to be a supplemental component. Supplemental components are localized
systems, such as kitchen and bathroom fans.

How should the Energy Advisor prepare the HOT2000 file for submission to the service
organization?
A) The energy advisor models the house in HOT2000, saves the calculations as an
"h2k" file and submits the house evaluation file to the energy service organization;

"hse" file and submits the house evaluation file to the energy service organization;
C) The energy advisor models the house in HOT2000 and saves the calculations as an
XML file. The homeowner submits the house evaluation file to the energy service
organization;
D) The energy advisor models the house in HOT2000 and saves the calculations as a
TXT file. The homeowner converts the house evaluation file into a Homeowner
Information Sheet using the Report Generator and submits it to the energy service
organization. - correct answer A) The energy advisor models the house in HOT2000,
saves the calculations as an "h2k" file and submits the house evaluation file to the
energy service organization;
An energy advisor must be affiliated with a licensed service organization and registered
with Natural Resources Canada prior to offering energuide Rating System services.
, Among the following, which is not relevant to the registration requirements for energy
advisor candidates?
A) Demonstrate proficiency by passing the Foundation Level Exam and Energy Advisor
Exam;
B) Provide proof of possession of a home warranty number or its provincial/territorial
equivalent to the service organization(s);
C) Complete probationary files to the satisfaction of the service organization's quality
assurance specialist;
D) Provide proof of a Criminal Record Check to the service organization's manager. -
correct answer B) Provide proof of possession of a home warranty number or its
provincial/territorial equivalent to the service organization(s);
In case of solid-fuel burning equipment, the energy advisor should collect the following
information:
A) Equipment manufacturer and model, whether the damper is open or closed;
B) Equipment type, flue diameter, whether the damper is open or closed;
C) Equipment type, flue diameter, and the temperature of exhaust gas;
D) Equipment type, flue diameter, the temperature of exhaust gas, and the radiation
loss level. - correct answer B) Equipment type, flue diameter, whether the damper is
open or closed;
